Permanent magnet synchronous motor drives are widely used in industrial applications because of their high performance. The use of field orientation control strategy gives external characteristics similar to those of well known dc drives without the need for slip rings and a field supply. In this paper we propose a new scheme for adaptive position control of a PM synchronous motor drive. This scheme employs an estimation method based on the Kalman filter theory. The algorithm can estimate the load torque and inertia moment quickly. The estimated torque is supplied to the PM synchronous motor to realize load compensation so to obtain no steady-state error and little transient-state position error. The speed feedback P-controller gain is adjusted by emploing the estimated inertia to avoid underdamped transient response. Numerical results are also shown.

Abstract

Permanent magnet synchronous motor drives are widely used in industrial applications because of their high performance. The use of field orientation control strategy gives external characteristics similar to those of well known dc drives without the need for slip rings and a field supply. In this paper we propose a new scheme for adaptive position control of a PM synchronous motor drive. This scheme employs an estimation method based on the Kalman filter theory. The algorithm can estimate the load torque and inertia moment quickly. The estimated torque is supplied to the PM synchronous motor to realize load compensation so to obtain no steady-state error and little transient-state position error. The speed feedback P-controller gain is adjusted by emploing the estimated inertia to avoid underdamped transient response. Numerical results are also shown.
